Study Of Thermal Stress Of Steel Slag Foundation

摘要

Building on the foundation with steel slag as a typical example of the destruction of the thermo-elastic theory to study slag landfill foundation, combining academic knowledge mechanics, heat transfer, etc., the theoretical foundation of slag analysis and numerical simulation of thermal stress, a comprehensive discussion the failure mechanism of the upper part of the foundation of the slag building. On-site measured temperature were fitted by thermal stress analysis of steel slag field, get the corresponding stress-strain cloud. The results show close to the simulation results and the actual situation: simulating thermal stress results slag surface be uplifted 3.77cm, uplifting 5cm of building fundamentals actual.
